IMPROVEMENT IN COMBINED OVERFLOW AND OUTLET CONNECTIONS FOR BOWLS, &c.

Specification forming part of Letters Patent No. 208,044, datedSeptember 17, 1878; application filed March 8, 1878.

To all whom it may concern:

Be it. known that I, WILLIAM E. SHER- RIFFs, of Boston, county ofSuffolk, State of Massachusetts, have invented an Improvement inOombined Overflow and Outlet Oonnections for Bowls, Sinks, &c., of whichthe following is a specification:

This invention relates to improvements in combined overflow and outletconnections to be used with lavatory or wash-bowls, sinks, 8m.

The invention consists, primarily, in a compound pipe which connects theoverflow with the outlet at the base of thebowl, such pipe being joinedwith a waste-pipe; also, in the combination, with a compound pipeconnected at its ends with the overflow and outlet, of a waste-pipehaving a return-bend to form a watertrap, substantially as hereinafterdescribed.

The drawing, in full lines, shows the compound pipe and waste-pipe withreturn-bend connected to form a trap.

The compound pipe a, shaped preferably as shown in the drawing, and madepreferably of cast-lead or other lead compound, is adapted to beconnected at its end 2 with the usual coupling-pipe at the outlet orwaste opening at the bottom of a bowl or sink, in the usual way, and theend 3 .will be joined in any suitable way with the usual overflow.

The dotted lines above the ends of the compound pipe represent a bowl.

At the curved portion 401:" the pipe to are added at top and bottom, andfirmly secured, sleeves b 0, each provided with screw-threaded portions.

The sleeve b receives, as in full lines, aloose coupling-nut, d, whichsurrounds the returnbend e at the end of the waste-pipe e, and,cooperating with a flange at the end of 0 within the nut d, holds theend of the waste-pipe and sleeve 1) closely together, a suitable packingbetween them preventing leakage 'of water.

Upon the sleeve cis placed acap, f, to cover it water-tight.

The end 7 of the waste-pipe will be continued downward, or joined in anyusual waywith a pipe, to carry the water discharged from the bowl to acloset or other suitable place.

It is obvious, with the parts constructed and connected as so fardescribed, that the water passing through the usual plugged outlet atthe bottom of the bowl, or from the usual overflow-openings at the topof the bowl, will be obliged to 110W upward and away through thereturn-bend and waste-pipe, and that a certain portion of such waterwill always remain in the curved lower portion of the compound pipe, andwill act as a trap to thereby prevent sewer-gas coming into the roomthrough either the unplugged opening at the base of the bowl or theoverflow-openings.

If it is desired to remove sediment or other matter from the compoundpipe a, the cap f may be removed, giving free access to the trap.

In cases where the waste from the bowl passes to a good and eflicienttrap located in the closet, then, if desired, the capf may be appliedupon the sleeve 1), closing it, and a pipe (designated by dotted linesm) or a tailpiece may, by a loose nut, like (I, be connected with thesleeve 0, and lead the waste-water directly to the closet.

Instead of the particular return bend described, I may use any otherequivalent connection with the bent portion 4 of the compound pipe whichwill maintain the water sufficiently high in the legs of pipe a toprevent the passage of air or gas.

I claim- 1. The compound pipe adapted tobe'connected with the outlet atthe bottom of a bowl or sink and the overflow-opening, as described.

2. The compound pipe adapted to be connected with the outlet at thebottom of a bowl or sink and the overflow-opening, as described, incombination with a return-bend to maintain the water in the compoundpipe at the proper level to form a trap, substantially as described.

3. The compound pipe, bent as described, and the threaded sleeves b c,combined with a waste-pipe and a cap, to operate substantially asdescribed.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

WILLIAM E. SHERRIFFS.
